cummulative sum elements in array(one by one)

[logatto]

Hi, any smart method for cumulative sum 2D? I cannot find anything better than using array subset, which is not the best for big matrix like images.

Thank you.

Hi logatto,

please define the cumulative sum for your 2D array!

Row-wise? Column-wise?

And please attach what you have done until now...

It is so helpful when someone asks a vague question (what do you mean by "cumulative sum elements in array" -- by rows?  by columns?  spelled with only one "m"?), and fails to attach any code to indicate to us (a) what version of LabVIEW they are using, (b) how much LabVIEW experience they may or may not have, and (c) the likelihood that the "real question" is "Please do my homework for me".

Please address these issues.

Hi, it was indeed easier than expected, I was taking it in the wrong direction.

I am sorry for having annoyed you with my vague question. Even if did not get the point of my single "m".

In my book you are OK!

You see this forum is all about LabVIEW and (aside from spelling LV correctly with the last four letters being capital letters) proper spelling and syntax simply does not matter. But be aware that if your wires are not straight and are running backwards, then you are in for a world of hurt!

So there!

Spoiler

It was news to me that summ was spelled with two 'm"s but it makes sense since summary has two "m"s.
